DUST-COLLECTOR FOR BEATING-MACHINES'.

Application filed September 4, 1918.

To all whom it may concern:

Be it known that I, RALPH OLLEo, a sub ject of the King of Italy, and aresident of New York, in the county of New York, State of New York, haveinvented certain new and useful Improvements in Dust-Collectors forBeating-Machines, of which the following is a true and exactdescription, reference being had to the accompanying drawings, whichform a part thereof.

My present invention has for its general object to provide a simple andeffective collecting screen for the dust and the like carried by astream of air discharged bypneuma'tic dust collecting apparatus. Myinvention was especially devised for use in, and as a part of a furbeating machine, such as is disclosed in my prior Patent,

Number 1,229,778, granted June 12, 1917,

wherein the dust, hairs and other fibers beaten out of a piece of fur orfabric being cleaned or renovated is sucked by a fan into a dust and airconveying conduit, and specific objects of the invention are to provideimproved means for straining the dust, hairs or fibers out of the streamor air set in motion by the fan, which may be readily incorporated inthe beating machine with a minimum of addition to its cost and bulk, andwhich may-be readily taken apart when necessary for cleaning, inspectionor repairs.

The various features of novelty which characterize my invention arepointed out with particularity in the claims annexed to and forming apart of this specification. For a better understanding of the invention,however, and the advantages possessed by it, reference should be had totheaccompanying drawings and descriptive matter in which I haveillustrated and described the best form of my invention now 'known tome.

Of the drawings:

Figure 1 is an elevation of a fur beating machine equipped with myinvention.

Fig. 2 is a vertical section through the dirt screening and collectingportion of the machine shown in Fig. 1.

Fig. 3 is a plan view of a portion of the dust screen, and

Fig; 4 is a view showing a detail of con struction.

The beating machine shown in the drawings in which my invention isincorporated comprises a work table A, beater sticks B,

operated by mechanism not shown for beating fur or other materialresting on the table A, and a dust collecting hood or conduit G intowhich the dust, hair or fibers loosened from the work by the. action ofthe beater sticks is sucked by the action of a fan K. Beyond the fan Kthe dust collectlng conduit comprises a downturned portion C, whichterminates, as shown, slightly below the level of the table A, the lowerend of the conduit portion being outwardly flared as indicated at C Apervious flexible tubular member E is detachably secured to the lowerend of the conduit section C. Advantageously the tubular member E isformed of jute bagging or the like relatively heavy fabric textile, andis provided at its upper end with a hem and with an elastic gatheringstring or belt element H located in the hem. The element H mayadvantageously be formed, in practice, (see Fig. 4) of a maininextensible section of cord or the like, and an extensible section Hcomposed of spring wire coiled into a helix. The gathering stringelement H serves to hold the upper end of the member E snugly about theoutwardly flared lower end C of the conduit section C. The lower end ofthe member E is secured to the periphery of an annular member F, whichmay advantageously be formed out of sheet metal Stamped into the form ofa shallow cup with a large central hole in its bottom surrounded by anuprising flange portion F. This provides a circular dirt collectingtrough F between the outer side of the flange F and the inner side ofthe cup body proper. Advantageously, the upper end of the body of themember F is outwardly flared, and has lugs F or outwardly bentprojections secured to its periphery at intervals. Advantageously thelower end of the tubular pervious member E is detachably secured aboutthe body of the member F by means of an elastic gathering string HA,which may be similar to the gathering element string referred to aboveand is received in a hem formed at the bottom of the member E. A conicalscreen element G is secured to the upper end of the flange portion F ofthe member F. The conical screen G advantageously consists of a bodyportion formed of fine mesh wire screen which is soldered at its base tothe upper end of the flange F. Advantageously a thin woven fabric G,such as cheese cloth,

covers the woven wire body portion of the screen G The member E andannular bottom member F are inclosed in a housing D through the upperend of which the lower portion of the dust conduit C projects. Thehousing D is provided with a removable side or door section D, and isformed with screen covered window openings D adjacent its upper end andlocated in the sides of the housing and in the door section D. The

bottom wall of the housing D is located at some distance below thebottom of the member F and supports a water pan I, the upper edge ofwhich is located slightly below the bottom of the memberF, so that thewater pan I may readily be removed when the door section D of thehousing is opened.

In operation the dust and dirt laden stream of air drawn through theconduit C by the action of the fan K is discharged into the pervioustubular section E through the lower end of the conduit section C. Fromthe space within the tubular section E the air may escape outwardlythrough the porous section E proper, or inwardly through the screen G.In either event the major portion of the dust, hairs, fibers, or otherdirt carried by the air, is strained out and deposited against the innerwall of the tubular element E and the outer surface of the conicalscreen G. Preferably the screen G should be more porous than the fabricforming the tubular screen E when the two screens are equally clean, sothat the major portion of the dust escaping with the air will passthrough the screen G and will impinge on the water in the pan I. The airafter escaping from the interior of the tubular screen E into thesurrounding housing D, passes out of the latter through the windows D Inpractice, after the apparatus has been in operation for some time,fibers and hairs will collect upon the conical screen G to such anextent as to materially decrease the porosity of this screen and inconsequence a relatively greater portion of the air entering the tubularscreen portion E will then be discharged directly through the latterwhen the screen G is not thus clogged by hair or fiber. At all times,however, the pervious tubular section E increases the availabledischarge area and reduces the back pressure effect on the fan of thedirt arresting screens. When necessary to take the apparatus apart forcleaning or for other urposes, the member F with the screen (E attachedthereto may be readily disconnected from the pervious tubular element E,either with or without disconnecting the latter from the conduit sectionC. This taking apart of the apparatus is facilitated by the flexiblecharacter of the member E. When the apparatus is thus taken apart, dust,hairs, fibers or the like collecting on the outer surface of the scribedthe best form of my invention now known to me, it will be apparent tothose skilled in the art that changes may be made in the form of theapparatus disclosed without departing from the spirit of my invention,as set forth in the annexed claims.
